Very interesting!!
Weird I could not find the cone material listed anywhere.
Best,

From the specification sheet:
"Geometrically reinforced ceramic cone for optimum piston operation and reduced break-up"

It is a ceramic cone or a ceramic coated metal cone ?
Might also be ceramic coated paper, Focal made cones like this and called them W glass, Silver Flute too, i guess a chimical treatment leaving a mineral coating at both faces of the cone...
Break up modes are strong but somewhat scattered.
Regarding these SBA, the 8' is interesting, the rest me-too midwoofers as plenty on the market, nothing new under the sun, simply more choice for diyers...

Doh!!
The W has a foamed rohacell core if I don't mistake, don't know how they coat the "glass" but the surface is not smooth, a little like grain of sand...
Or it's FauxCal !
There are finally many drivers makers which took the idea of a sandwich with a foam core structure : also B&W ? The brand also than Focal Audio speakers chose... iirc.

Yes, you are absolutely right, i was refering to a former cone treatment Focal called Polyglass, applied on paper...

In the case of the 8' model, SBA stuff doesnt look super rigid...
But i like this little chaos, guess it is less irritating than one strong peak. Might sound like a Lowther...

An externally hosted image should be here but it was not working when we last tested it.

IMHO, if you are looking for the world stiffest cone, you should look at the Morel Carbon fiber/Rohacell/Carbon fiber cones woofers.
Unbeatable.

Damned french, it must be wine proof...
"a sandwich, a glass of wine, la vie est belle !" (You was thirsty, Focal made it !)

Mmm... This is for me the contrary of rigid, with controled multiple break up modes, as most full rangers work.
Rigid like ceramic or diamond gives one strong peak at break up.

So one thing that is kind of weird is that despite being ceramic, they also seem to use the standard 3-part construction. Cone, dust cap and voice coil former.
Actually it's weird any metal cone driver does this too.
Wonder why. I mean if I was going to go through the trouble of making a pure ceramic driver, I would at least eliminate the dust cap.
